You should use $HTTP_POST_VARS (or $_POST) all of the time. There's security risks in
using register_globals. It's not risky in all cases. But register_globals will allow
arbitrary variables to be added to into the name space of your script by simply
putting them on the uri. Code not expecting such input, and expecting variables not
to exist unless the script set them may behave unexpectedly.
The reason the variable is not set is that the checkbox isn't checked. You can test
the variable with isset(), or empty() before you use it so you don't get the warning.
To learn what your script it seeing when you submit the page, do a:
foreach ($HTTP_POST_VARS as $key => $value) {
echo "Key: $key Value: $value<br>\n";
}
at the top of your action handler script, and watch the variables come in when you
check or not check the checkboxes. Once you understand that, then write the code to
handle the situation.
